Detroit Steel Products Company 


BN introducing our Wrought-Steel Detroit-Fenestra Sash (patented), in standard sizes, we believe that we are 
| taking a step in the manufacture of metal sash for which the market is prepared. “The Architect and Builder 
will readily appreciate the advantages derived from the use of a standard sash from the standpoint of delivery 
and erection, while from the manufacturing standpoint it may be said that the adoption of the standard so 
materially reduces the cost of the sash as to make metal sash nearly as inexpensive as the ordinary wood sash, under 
equal conditions. 

Through this booklet we desire to place in the hands of those who may be interested, all information necessary 
for preliminary planning and estimating, and we request that it be filed for future reference, believing that it will be 
useful whenever our product comes under consideration. 


HORIZONTAL 
BAR 
"Fenestra" 
Like other great inventions, the process is per- 
fectly simple, the only wonder is that it has never VERTICAL 
been thought of before. On this page are a few BAR 


illustrations which will suffice to show you how the 
Fenestra joint is made. 


A small cross slot is made in the vertical bar 
(only sufficiently large to allow the flange of the 
horizontal bar to pass through), the moulded por- 
tion is then pressed out so as to fold closely round 
the moulded portion of the horizontal bar. 


All that happens to the horizontal bar is that 
a small notch is made in it to act as a lock. From 
this it will readily be seen that the amount of metal 
removed in making a Fenestra joint is compar- 
atively infinitesimal. This allows a far lighter 
section to be used than is possible with the mitre 
jeint or any other joint, thus making a great saving 
in the weight of the material used and consequently 
in the ultimate cost of the sash.

Facts About "Fenestra" 


Fenestra Steel Sash are manufactured from specially rolled, solid sections, and the 
composition of the material is such that we are able to furnish a sash which has at once the 
strength of steel and the weather resisting qualities of iron. 


Because of the strength of our Fenestra joint, it is possible for us to use sections which 
permit of 25% more light being delivered through a given opening than has heretofore been 
possible. 


By making a sash which requires no frame, sash weights, etc., or heavy mullions, we 
eliminate the cost of same, thereby reducing the cost of each sash to a minimum. 


Fenestra looks better than any other sash. A natura! curve at each joint breaks the 


monotony which is characteristic of other sash, and gives Fenestra an appearance which is quite 
its own. 


Fenestra was designed to supply a demand for a metal factory sash. It is not intended 
for installation in office buildings, but for its special purposes, it has no equal: as combining 


simplicity and neatness, with strength and weather and fire resisting qualities. 


Detroit Steel Products Company 


The Design of "Fenestra" 


The cost of Fenestra is governed by the quantity of material involved, the size and 
uniformity of the openings into which the sash are to be installed and the amount of ventila- 
tion required in each sash unit. We aim, therefore, to obtain information regarding prospective 
work at a time when it is not too late for us to advise with our customers concerning details 
of building construction. In this way we are able to give you the benefit of our experience, 
and, at the same time, make our proposition attractive by offering at their full value and 
least cost, the advantages which our construction affords. 


This pamphlet will serve to give you some idea of what Fenestra is; for detailed 
information we refer you to our estimating department, which is organized especially for 
consultation with our customers. 


Sections 


It must be understood that but two sections are used in the construction of types "A", 
"B" and "C" Fenestra "Standards", viz. the double flange section, number 92, which forms 
the outside members of the sash, and the inside sash section, number 90, which is used 
only for making the inner bars (both vertical and horizontal). See page 6. Other outside 
sections are used in special cases and for special sash, but the one shown may be applied 
in such a variety of ways that it can be used for ordinary sash almost without exception. 
Type "M" standards have No. 94 section top and bottom (see detail).

Fenestra "Standards" 


We would call your attention to the fact that_the use of standards in 


Fenestra neither restricts the size of the window nor the percentage of ventila- 


tion which may be obtained from a given opening. 


By selecting a sash of the required height, the width may be varied by 
using multiples of this sash unit. 


Ventilation may be arranged to suit practically any requirement by the 
use of the desired single unit or a combination of unventilated sash with those 
which are provided with ventilators. All units of the same height are inter- 
changeable. 


Standards in Fenestra are designed to take 10"x 16" and 12"x 18" 
standard size glass, Type “A” Sash, 10"x16" and Types “B,” “C” and “M” Sash 
12"x18" glass. 


As before mentioned, Fenestra ‘‘Standards” are designed to take 
10"x 16" or 12"x 18" glass. In order that these sizes may be fitted without 
trimming, the sash is laid out as shown by the accompanying cut, which 
illustrates the spacing of horizontal bars in Sash Al2. The following formula 
may be used in calculating the dimensions of standard sash, and, in fact, any 
sash the outside members of which are formed from Section No. 92, by sub- 
stituting measurements as indicated: 


N x (Glass dimension (height or width) + 3g") + 7%" 
— over-all dimension of sash. 
N = number of divisions in height or width of sash. 


On page 17 we illustrate the method which is almost universally used for 
the erection of Fenestra in brick work openings. In the case of concrete, the 
same sections are used, but the methods for installation in concrete are so varied 
that we advise consultation direct with us when questions arise on this point, but 
suggest detail on page 24. 


We supply the sash complete with glazing pins, and hook bolts at head 
and flat bar lugs if required. 


We do not however supply any collateral construction such as angles 
or other steel work to carry walls above sash.

Instructions for Erection 


The sash leaves our factory complete with necessary lugs for fixing to brickwork and bolts for attaching same to sash, screws for 
assembling mullions (where any) and hook bolts for attaching the head to structural work, when structural work is used. In the case 
of ventilated sash the ventilators are kept in position by wooden wedges and twine, care must be taken that these wedges are not 
removed until the greater part of the sash is glazed. 


The sash should be stood on the sill of the opening which it is to fill, in its correct position, with the lugs at sides, head and sill, 
When same are used, in position. It should then be plumbed for square and perpendicular. The sides of the sash then serve in a brick 
building as a guide for the bricklayer and all that is asked of him is that he shall fill the channel of the frame with pointing as his 
wall goes up. 


It should then be understood that the sash will carry no weight on its head, and when the walls of a building continue above the 
sash, adequate structural work must be provided to support the brick work. This is best done by having two angles, two channels, or 
two I beams running across the top of the opening and kept sufficiently far apart to allow the head of the sash to just stand be- 
tween them. See pages 17 and 25. 


In all special cases and for concrete buildings, special instructions will be sent to meet the peculiarities of the case. 


Instructions for Glazing 


The sash leaves our factory painted one priming coat and with a supply of metal pins for holding the glass and re-enforcing the 
putty. Unlike other sash it is glazed in position, and, in all cases, from the inside or the building. Better results can be obtained by 


painting the sash another coat of the finishing color before glazing. It is also a good plan to have the putty tinted final color of the 
sash where finish is an important factor. 


With regard to putty, to obtain quick drying and for general satisfaction it is essential to use putty of the best quality, graded 
with litharge. Also work in some japan dryer just before using. Ordinary putty of light consistency must not be used. 


In case of ventilated sash, the wooden wedges with which these are provided when they leave us, should not be removed until the 
glazing cannot be carried on any further without taking them out, as they tend to hold the ventilator square and give it the correct 
clearance all around. 


Glass must be back-puttied, that is to say, bedded in putty, and this back-puttying must be struck off flush on the outside so as to 
allow no ledge for the accumulation of water. 


The sash bars in standards are drilled to take either 1” or 14” glass thickness. 


Instructions for Ordering 


1. Designate clearly by letter and number that standard required; in the case of near standards say whether ventilated or not, 
and give sketch showing amount of ventilation and location of ventilator. 


2. State whether vents are to be used singly or in combination in the openings. 

3. In the case of multiple unit openings state how mullions are to be prepared at head and sill. 
4. State thickness of glass to be used. 

5. State type of wall construction (i. e. brick, concrete, etc.)
